Changelog
=========
* :feature:`16` **Python 3 support!** Our test suite passes under Python 3, and
it (& Fabric's test suite) continues to pass under Python 2.
The merged code was built on many contributors' efforts, both code &
feedback. In no particular order, we thank Daniel Goertzen, Ivan Kolodyazhny,
Tomi Pieviläinen, Jason R. Coombs, Jan N. Schulze, ``@Lazik``, Dorian Pula,
Scott Maxwell, Tshepang Lekhonkhobe, Aaron Meurer, and Dave Halter.
* :support:`256 backported` Convert API documentation to Sphinx, yielding a new
API docs website to replace the old Epydoc one. Thanks to Olle Lundberg for
the initial conversion work.
